DNA Sequencing Methods and Technologies
- Dideoxynucleotides are incorporated during DNA strand replication in Sanger sequencing, the first generation of DNA sequencing.
- Pyrosequencing was introduced in the second generation of DNA sequencing, characterized by real-time sequencing.
- Illumina sequencing technology largely replaced pyrosequencing in second-generation sequencing methods due to its high efficiency.
- Next-generation sequencing (NGS) techniques provide higher throughput than pyrosequencing; Illumina sequencing is among those advanced NGS methods.
- Pyrophosphate release during DNA synthesis is detected in pyrosequencing and is central to its sequencing process.
- Sanger sequencing is the main technology used in the first generation of DNA sequencing, utilizing chain termination.
- Advanced NGS methods have largely replaced pyrosequencing, offering improved throughput for large-scale sequencing projects.
